Double plunger screen changer for modified granulation

Modified granulation raw materials have fewer impurities and higher value. In terms of the selection of wire hydraulic extrusion screen changers, double column and double station wire screen changers are generally selected for wire rod production to achieve the goal of continuous wire screen changing. It is suitable for production requirements such as granulation, pipes, sheets, chemical fibers, cast films, and various chemical solvents that require uninterrupted material flow and high continuity.

The screen changer for modified granulation adopts a dual column and dual channel design, with internal heating, fast heating, and uniform temperature. During normal production, both filter screens work simultaneously. When replacing the filter screen, one filter screen works and the other filter screen is replaced. A material introduction and exhaust device is designed, which is controlled automatically or manually to achieve non-stop screen change, no material leakage, uninterrupted material flow, small material pressure fluctuation, little impact on production, and good continuity.
